i have just added a denon dca-800 amp to my install,running both f+r speakers and a pioneer sub.....so with my cd,thats 16 leads/cables.
could somebone please offer some advice as to how to make all the wiring look neat&tidy?..... and not like the'snakes wedding'which i have just stuffed in the bootwell for the moment...any help will be most appreciated

 

...that's what the carpet's for

More seriously, cut the cables, cable tie the non-noise-inducable ones together and hide em in cable runs.
